Why were the Boston Celtics able to limit Orlando Magic C Dwight Howard to five points on just seven shot attempts in the Magic's Christmas Day defeat at Amway Arena?

Celtics coach Doc Rivers said afterward that his team didn't do "anything special," but Celtics C Kendrick Perkins offered a less delicate answer.

"You've got to play him physical. You watch other teams around the league, they pretty much let him set up shop," Perkins said, according to The Associated Press. "You've just got to go in and be prepared to go to war. You've got to fight him first, hit him first. . . . He likes to be physical, but he doesn't like anyone to be physical with him."
